DescriptionGitHub Advisory

WWBN AVideo is an open source video platform. In 29.0 and earlier, plugin/AuthorizeNet/processPayment.json.php credits the logged-in user's wallet based only on the attacker-controlled amount POST parameter. The endpoint contains a TODO for real Authorize.Net charging, hardcodes $paymentSuccess = true, and then calls YPTWallet::addBalance() without validating any Authorize.Net transaction, webhook signature, hosted payment token, nonce, or server-side payment record. This allows any logged-in user to add arbitrary funds to their own AVideo wallet when the AuthorizeNet and YPTWallet plugins are enabled.

AnalysisAI

Wallet balance forgery in WWBN AVideo 29.0 and earlier allows any authenticated user to credit their own wallet with arbitrary funds by abusing an unfinished AuthorizeNet payment handler. The plugin/AuthorizeNet/processPayment.json.php endpoint hardcodes payment success and calls YPTWallet::addBalance() using an attacker-supplied amount with no validation of the underlying Authorize.Net transaction. …

Vulnerability AssessmentAI

Exploitation Requires an authenticated AVideo user session (PR:L) and the target instance must have both the AuthorizeNet plugin and the YPTWallet plugin enabled, which exposes plugin/AuthorizeNet/processPayment.json.php and the addBalance() sink. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment CVSS 4.0 scores this 7.1 with vector AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N - network-reachable, low complexity, low privileges (authenticated user), no user interaction, and a high integrity impact with no confidentiality or availability effect, which accurately reflects a financial-integrity bug rather than a system-takeover. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker registers a normal user account on a target AVideo site running the AuthorizeNet and YPTWallet plugins, then sends an authenticated POST to plugin/AuthorizeNet/processPayment.json.php with an inflated amount field. The server skips the unimplemented Authorize.Net charge, treats $paymentSuccess as true, and YPTWallet::addBalance() credits the attacker's wallet, which can then be spent on paid content, withdrawn, or used to defraud the operator. …
Remediation No vendor-released patched version was identified at time of analysis; consult GHSA-9392-pj54-qqf8 at https://github.com/WWBN/AVideo/security/advisories/GHSA-9392-pj54-qqf8 for the upstream fix status and upgrade once a tagged release supersedes 29.0. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Disable the /plugin/AuthorizeNet/processPayment.json.php endpoint via web application firewall rule or uninstall the AuthorizeNet plugin entirely; audit all wallet balance changes from past 30 days for suspicious additions. …
